16.3.6 Data description (MD)
13070 DRIVE_FUNCTION_MASK
MD number Bit-coded screen for selecting the functional scope expected by the NCK with PROFIBUS
drives
Default settings: 0 min. input limit: 0 max. input limit: FFFF FFFF
Changes effective after power ON Protection level: 2/7 Unit: –
Data type: DWORD valid from SW: 2.1
Meaning: Meaning of set bits:
Bit 0: Deactivation of the 611U-specific drive alarm mapping
Bit 1: Deactivation of the 611U-specific drive type detection
Bit 2: Deactivation of the 611U-specific parameter accesses encoder drivers
Bit 3: Deactivation of the 611U-specific parameter accesses output drivers
Bit 4: Activation third-party drive: DSC bits (CTW1.12/STW1.12)
Bit 5: Deactivation of the 611U-specific drive parks (CTW2.7/STW2.7)
Bit 6: Deactivation of the 611U-specific travel to fixed stop (CTW2.8/STW2.8)
Bit 7: Deactivation of the 611U-specific motor changeover internal (STW2.9–11)
Bit 8: Deactivation of the 611U-specific ramp block (CTW1.13)
Bit 9: Deactivation of the 611U-specific function generator functions (CTW1.8/STW1.13)
Bit 14: Selection of non-cyclic DP communication: 0=DPT; 1=DPV1
Bit 15: Deactivation of consistency check for PROFIBUS message frame configuration
CTW: Control word (PDA word in the PROFIDrive message frame to DP slave)
STW: Status word (PDA word in the PROFIDrive message frame from DP slave)
PDA: Process data
MD irrelevant with ...... –––
37620 PROFIBUS_TORQUE_RED_RESOL
MD number torque reduction resolution on PROFIBUS (LSB weighting)
Default settings: 1 min. input limit: 0.01 max. input limit: 10
Changes effective after NEWCONF Protection level: 2 / 7 Unit: %
Data type: DOUBLE valid from SW: 2.2
Meaning: For the drives connected via PROFIBUS, the MD defines the resolution of the torque re-
duction transferred in the cyclic SIMODRIVE standard message frames 102 to 107 (control
word: TorRed). The torque reduction is e.g. required as part of the function “Travel to fixed
stop” (FXST).
At automatic adjustment, the machine data must be set so that it is consistent with the
meaning of drive parameter P0881: “Torque reduction evaluation”; or with manual adjust-
ment with the drive-end interpretation of the control word: TorRed.
The default value of 1% corresponds to the resolution that was valid prior to SW 2.2.
